Before going to fly yesterday, as usual I checked all I can find on weather (Metar, TAF, weather depiction chart, wind aloft....). They all agreed that it was going to be mostly a good day to fly. The wind aloft was reporting some strong wind. I went flying and as it said....wind showed up in the afternoon with some gust to the 20/25 knots. It was a bumpy ride. As soon as I came back home, I took a screenshot of the Surface Analysis Chart (http://pasteboard.co/158EGW9o.png) . I thought that it was possible to predict the strength of the wind by how close the isobars are on the chart. So what am I missing there. How come the isobars do not seem to show a strong wind then.
ps: I was flying in the East Tennessee Region (marked by the red circle).
Also, another stupid question. I thought that a cold front (or a warm front) usually means bad weather. So home the day was a good day to flight with the cold front above our head that day !
